  • Introduction: Colorectal cancer is the second deadliest cancer and the third most common cancer in the world after prostate cancer in men, breast cancer in women and lung cancer, which is more common in men than women. Colorectal cancer is one of the few cancers that screening, early diagnosis and timely treatment can significantly control it. Therefore, familiarity with this cancer, identifying the causative agents, diagnosis, treatment, etc. is very important. This article addresses this issue.​
  • Methods: This research is a review study and, in this research, Iranian and foreign databases such as PUBMED, NCBI, etc. have been used to collect information.
  • Results: According to the findings, the increase in colorectal cancer is increasing in developed countries, and this is due to the growing population, modern unfavorable eating habits and increasing risk factors such as smoking, low physical activity and obesity.
  • Conclusion: According to studies and documents, environmental and genetic factors play a major role in the pathogenesis of colon cancer. The role of nutrition in colon cancer has also been studied and the results indicate that it is an effective factor in creating or protecting against this cancer.
